Introduction

The information below is taken from a Walker-Turner service bulletin that dates from about 1961.

With respect to serial numbers we can divide Walker-Turner's existence into five epochs:
  • Type 0: No serial numbers. Early machines did not have any serial numbers.
  • Type 1: The first serial number system began in 1939. These followed no logical pattern and were more akin to a model number than a unit-specific designation. See the machine-specific section below for details. Note that although the original document lists serial numbers with dashes, the numbers that were stamped onto the badges often used a space instead.
  • In 1948 Walker-Turner was sold to Kearney & Trecker. At some point thereafter the tags were changed to read "Walker-Turner Division of Kearney & Trecker".
  • Type 2: Starting in April of 1950 a new system was introduced. These new serials are formatted YYMSQD where YY is the year of manufacture, M is the type of machine, S is the specific model of machine, Q is the quarter of the year of manufacture, and D notes deviation from the standard model. For example, 52DA2A is a standard (52DA2A) single-spindle (52DA2A) 15" drill press (52DA2A) that was built in the 2nd quarter (52DA2A) of 1952 (52DA2A). Below is a list of the machine type code letters and what they stand for.

  • Type 3: The next serial number system was introduced in April 1953 and used until September 1956. Each machine was numbered 0000001, 0000002, etc. The type and model cannot be identified by the number alone. Machine tags used during this time included fields for both Model No. and Serial No. Almost all of the models sold during this time were introduced in 1953.
  • In May of 1956 Kearney & Trecker sells its Walker-Turner Division to Rockwell. At some point thereafter the tags were changed to read "Walker-Turner Division of Rockwell".
  • Type 4: The last serial number system began in October of 1956. The machine type is designated by a two-digit prefix, e.g., No. 11-0001 was the first 20-inch drill press as of October 1956. This system continued until Delta/Rockwell's serial number system replaced it. Walker-Turner machines with a Rockwell serial number badge should be dated according to the Delta Serial Numbers page. Most Rockwell built Walker-Turner machines came from either their Bellefountaine or Tupelo plants.

Detailed Information by Machine Type

The following subsections provide details of serial numbers for each type of machine made by Walker-Turner. Information that we have for each machine model is divided into the serial number Type that its production occurred within.

15-inch Drill Press

Type 1:
Each model number will be followed by its manufacturing dates, then by serial numbers used. Each serial number is linked to an example in the owwm.com Photo Index when one exists.

900 Series, 1940 through 1947: 9D140, 9D1040*, 9D943, 1-1140, 1-944, 1-147

* While two examples of serial number 9DP1040 have been entered into the Photo Index, none have been entered for 9D140, 9D1040, 9D943. This is likely a mistake in the original document.

Type 2:
For units with the Type 2 serial numbering system, the second letter indicates only the number of spindles or the type of spindle in the original unit. All units in this system were of the “900” series until the “1200” and “1300” series were introduced in the second quarter of 1952.

900 Series

900 Series Type 2 examples from the owwm.com Photo Index:
50DH2E, 51DM1A, 51DJ3A, 52D01A

1200 Series

The first “1200” series Drill Press was serial number 52DA2A which indicates “52” as 1952, “DA” 15” Drill Press, “2” second quarter and “A” standard model.

1300 Series

The “1300” 6” travel 15” Drill Presses are identified through the use of an “O” in place of the “D” in these serial numbers.

Type 3:
1200 Series

1200 Series Type 3 examples from the owwm.com Photo Index:
Model 1216-26 0000224
Model 1216-42 0000807, 0001028

20-inch Drill Press

Type 1:
Each model number will be followed by its manufacturing dates, then by serial numbers used. Each serial number is linked to an example in the owwm.com Photo Index when one exists.

1100 Series, 1941 through 1952: D11241, D11242, D11542, D11642 (PF), D1143, 2-1143, 2-644, 27-1144 (PF), 27-546 (PF), 2-546

Type 2:
For units with a Type 2 serial number, the second letter indicates only the number of spindles in the original unit. These 20” Drill Presses began with serial number 52EA2A which indicates “52” as 1952 year of manufacture “EA” 20” Drill Press, etc. All Serial numbers prior to 52EA2A were Type 1.

Bandsaws

Type 1:
Each model number will be followed by its manufacturing dates, then by serial numbers used. Each serial number is linked to an example in the owwm.com Photo Index when one exists.

BW740, 1950: 29-449

BN905 14” Wood, 1939 to 1950: OBS6390, 19-639, 19-1049

MCB1150 16” Wood, 1950: 32-1049, 50BD2A

MCB1151 16” Wood, 1950: 50BE2A

MCB1160 16” Metal, 1950: 50BF2A

Type 2:
For units with Type 2 serial numbers, the second letter indicates specific models of Bandsaws as follows:

“A” indicates BW740“D” indicates MCB1150
“B” indicates BN905“E” indicates MCB1151
“C” indicates BN905“F” indicates MCB1160

Thus serial number 50BB2A would indicate that it was a model MBN935. Serial number 50BF2A indicates model MCB1160, etc.

“900” Series Including RA901, RA901B, RA908 and RA909:
27-44928-449
27-114928-1149
27-54933-1149
34-1149

“1100” Series Including RA1104, RA1106, RA1107 and RA1108:
RA9390RA143WR
RA510RA343HB
RA541023-243
RA540RA343
RA640RA642
RA6423-1949
11RA343

Type 2:
For units with Type 2 serial numbers, the second letter will identify the machine as “900” or “1100” series as follows:

“900” Series Letters: RF RG RJ RT RV RW RY RZ

“1100” Series Letters: RA RB RC RE RK RL RM RN RX

At the time of the number change, the 900 series models were altered slightly and then called the *4200 series. The 1100 series became the 4100 series.

* Some 4200 series units were produced with an A. O. Smith direct drive motor. These proved highly unsatisfactory and were discontinued immediately. Some difficulties will arise on radial saw parts orders due to our lack of Parts Manuals and a lack of any manufacturing records. All orders for gearhead motor parts MUST include the “GB” number of the motor. This is our only positive identification of the motors since H.P etc....or manufacturer's serial numbers do not mean anything. Any questions on these machines should be referred to Headquarters Office. (Note: The preceding was kept intact purely due to the fascinating insight it provides into the service of these machines).

Cut-off Machines

Type 4:
All Model 8110, 8120, 8320, 8320-2 cut-off machines should have Type 4 serial numbers.
